CHARLES T. STUART, OF BROOKLYN, NEV YORK.

SPECIFICATION forming part of Letters Patent No. 307,350. dated October28, 1884-.

Application filed March 1, 1884. (No moe.)

To all whom t may concern:

Beit known that l, CHARLES T. STUART, of Brooklyn, Kings county, StateofNew York, have invented a new and useful Improvement inThill-Couplings, of which the following is a specication, referencebeing had to the accompanying drawings, forming part of the same, inwhich- Figure l is a side elevation of a thill-coupling embodying myinvention. Fig. 2is a top view of the same and a portion of an axle onwhich the coupling is secured. Fig. 3 is a section on line y y, Fig. 2;and Fig. 4 isacentral vertical section of apart of an axle and the saidcoupling.

My invention relates to a thill coupling formed of two clips on theaxle, between which the eye of the thill-iron is held by a pin passingthrough the eye; and it consists in the devices hereinafter describedand claimed.

A and A represent two clips secured upon the bolster B and axle C ofavehicle by straps D D and nuts c a in the usual Way. On the front legof each clip is formed a lug or jaw, b b', between which jaws the loopor hook E of the thill-iron is held by a pin, c. The jaw b is providedwith the said pin c, which projects from its side toward the opposite jaw, the free end of the pin passing through a hole in the latter. Thesaid pin is welded solid to the said jaw b so that when it is passedthrough the eye of the thill-iron and the hole in the opposite jaw thethill-iron cannot be detached from the pin except byloosening the clip Aand'sliding it on the axle, thereby uncovering the free end of the pinc. The clips are prevented from displacement on the bolster and axle bya strap or plate, d, let into the bolster under the clips and having itsends turned up, as seen in Fig. 4.

That I claim as my invention, and desire to secure by Letters Patent,is-

The /described thill-coupling consisting of the clip A', provided with ajaw, b', and pin c, solidly connected thereto, the clip A, pro videdwith a jaw, b, with a hole to receive the end of the pin c, and athill-iron provided with an eye or hook, E, through which passes thesaid pin, all constructed and combined as and for the purpose described.
